Rethkir: Response

Hey, thanks for taking the time to write to me. I appreciate this info very much.

"Is the PFGE max thrust figure obtained from running both inputs with premixed 60.7MPa fuel at 196 K?"

Yes, that is exactly what I did with Volatile/O2 mix. I didn't try testing it with N2O mix since it seemed convoluted, so I didn't update that value. Though at this point I have a better understanding of how to get it to work, so I might just test that for the sake of getting it on record.

"You can add up to 0.05 mol/L of frozen gases or liquids to a pipe network before it starts taking damage and i wonder if adding ~0.134% of frozen liquid nitrous oxide is enough to get another 100-200N of thrust."

Oh, that's very neat. I didn't know about this limit. So it would be a fuel mix with a tiny superfuel boost. Not practical, but kinda cool. I'll probably try it out before building an N2O PFGE.

And thanks for the coefficients. I saw someone posted them on Reddit, but this list is more comprehensive. I noticed that the 6.3 kPA min and 6000 kPA max defines the minimum and maximum liquid temperatures for some substances, but not others like CO2, N2O, and pollutants. Are those limits defined by the wiki values, or is there something more going on?

"Also, note frozen liquids linearly interpolate their evaporation pressures from their freezing point values at their freezing temperature down to 6.3 kPa at half their freezing temperature, see [1]. I'm not sure if there's an application where this is useful(open-cycle pollutant evaporation chamber for liquid oxygen?), but it's there"

Huh, so the phase change diagrams showing a vertical line aren't exactly accurate, then? Technically it should be a slope? Weird.

Nitrous Oxide, also referred to as N2O or Nitrous, is a reactive [[Gas|gas]] primarily used for it's role in the creation of [[Fuel#Gas_Fuel|Superfuel]]. Nitrous Oxide naturally occurs when smelting [[Ore_(Lead)|lead]] and [[Ore_(Silver)|silver]]. It can also be acquired by [[Ice Crusher|crushing]] [[Nitrice]]

= Details =
Nitrous Oxide will condense into Liquid Nitrous Oxide at a very low pressure and temperature. Due to this, Nitrous Oxide is best stored as a liquid above {{Temperature|252}}. Stationeers are advised to monitor pipelines when setting up Nitrous Oxide gas systems as ruptures may occur if the temperature remains unchecked.

Nitrous Oxide can be combined with [[Volatiles]] at a 1:1 ratio to create [[Fuel#Gas_Fuel|Superfuel]]. Superfuel combusts at {{Temperature|323.15}}, burning much hotter and quicker than [[Fuel#Gas_Fuel|Fuel]].

While Nitrous Oxide can be acquired through smelting ores and crushing ice, it can also be created via the [[Nitrolyzer]] using a combination of [[Nitrogen]] and [[Oxygen]].

== Notes ==
* For rocketry, Nitrous Oxide has a mass of about 21.7 mol/kg, giving the 1:1 fuel mix a mass of 42.1 mol/kg compared to 62.5 for a [[Fuel#Gas_Fuel|Fuel]] mix.
* Many Nitrous Oxide storage builds will include a [[Phase Change guide#Heating_.2F_Cooling_with_phase_change_loops|condensation trap]] to avoid pipe ruptures.

Rocket Engines

Rethkir: Updated values based on in-game wiki and testing

[[Category:Rocketry]]

Rocket Engines give you their max output in kN with this you can calculate what they can reasonably carry into orbit depending on the planet or moon you are on. Force = Mass * Acceleration. Acceleration is equal to the planet's gravity, Mass is given in kg per part of the rocket, and Force is kN. If your thrust force listed below is less than the weight of the rocket in kN then you will not even take off. It is better to have a thrust much higher than the weight of the rocket or else you risk running out of fuel on launch and on landing.

[[Gas condensation|Liquid propellants]] bring greater efficiencies. Using Nitrous Oxide as oxidizer provides excessive thrust values. Keep in mind that N2O fuel mix is 1.9375 times heavier at same moles, or 2.15 times heavier at same volume, while thrust boost is around 1.5-1.7. Engine efficiency determines "bonus" thrust multiplier, meaning engine with higher efficiency will give more thrust consuming same amount of fuel. Thus using liquid engines is more favorable if one can cool fuel down, moreover Pressure Fed Engines consume fuel inversely proportional to its temperature. On the other hand if [[Volatiles]] and [[Oxygen]] are in excess (e.g. farm on [[Vulcan]]) is may be much easier to opt for Pressure Fed Gas Engine. It will provide ~40kN at 20°C.

Carbon Dioxide, also referred to as CO2, is a non-flammable gas found in some atmospheres naturally (such as [[Worlds#Mars|Mars]]). It can also be produced by burning [[Fuel]] or [[Coal]], smelting most ores (e.g. [[Ore_(Iron)|Iron]], [[Ore_(Copper)|Copper]], and [[Ore_(Silicon)|Silicon]]) and through human respiration.

= Details =
Carbon Dioxide will condense into Liquid Carbon Dioxide starting at {{Temperature|265}}. With such a low temperature requirement, most setups will store Carbon Dioxide as a gas and use Liquid Carbon Dioxide as a [[Coolant|coolant]].

Carbon Dioxide is required for most plants to grow. Plants will inhale the Carbon Dioxide to create [[Oxygen]] which can be harvested using [[Active Vent|vents]]. Stationeers should monitor their plants to ensure they always have enough Carbon Dioxide as, given enough time, they can convert all of it into Oxygen.

Carbon Dioxide has an isochoric molar heat capacity of 28.2 J/mol⋅K, making it a superior coolant to [[Pollutant]] outside applications involving phase change where Pollutant can make use of its greater latent heat capacity. Both are greatly surpassed by water, though water is harder to find and has more important uses.

}}

== Description == 
<blockquote><q>Volatiles is a combustible fuel. It is refined from [[Ice (Volatiles)]]</q> 
'''- Stationpedia'''</blockquote>

'''Volatiles''' or '''H2''' is a combustible gas in the presence of Oxygen and the breathing gas of the [[Zrilian]] species. The main source of Volatiles on most planets is in the form of [[Ice (Volatiles)]] that can be mined on the surface. Volatiles will autoignite at 300 Celcius or above in the presence of [[Oxygen]], and autoignite at 50 Celcius or above in the presence of [[Nitrous Oxide]].

=== Composition ===
Denoted with the name ''Volatile'', it is a homogenous compound made up of Hydrogen, Chlorine and Hydrocarbons. This means that it is poisonous due to the Chlorine, but also combustible due to the Hydrogen and Methane portions and can be turned into [[Water]] with [[Oxygen]] in a [[Kit (Atmospherics) H2 Combustor|H2 Combustor]] that has a self-contained catalyst which helps free the Hydrogen atoms.

Possible compound: CH3Cl (Chloromethane)


== Usage == 
''See also: [[Fuel]]''

Different ratios of Volatiles and Oxygen will produce different temperatures and pressures during combustion. Combustion will create a large amount of Heat, pressure, and [[Carbon Dioxide]]. This reaction is useful inside a [[Furnace]] for smelting ores and creating alloys, but can be catastrophic when inside a [[Canister]] or a room.

Currently as of version v0.1.1089.5513, it is labeled in the atmospheric analyzer as H2, but it is not Hydrogen.<ref>Stationeer's Discord https://discordapp.com/channels/276525882049429515/392785541411635201/393216103284998144</ref>. When burned, it produces heat, [[Pollutant]]s, and [[Carbon Dioxide]] in the following reaction:

2 Volatiles + 1 O2 → 3 [[Pollutant|X]] + 6 [[Carbon Dioxide|CO2]] + 2×Enthalpyvolatiles heat energy

1 Volatiles + 1 [[Nitrous Oxide|N2O]] → 2 [[Nitrogen|N2]] + 2 [[Carbon Dioxide|CO2]] + 2×Enthalpyvolatiles<ref>Cows are evil youtube video https://youtu.be/-nELRhGK1_A?t=890</ref> heat energy

Enthalpy of volatiles is 286000 Joules, this is per amount of Moles of matter.

Since both reactions results in same amount of heat, but the one with Nitrous Oxide results with less moles, it produces much more heat per amount of matter (2.25 times more heat energy per mole of reaction products). Also, Nitrogen has lower heat capacity than pollutant, which results in even higher temperature.

This reaction is inconsistent with volatiles being simple hydrocarbons (too much CO2 is produced), but it may be consistent with more complex organic molecules. If either volatiles or oxidizer is below 0.3mmoles, it reacts completely without any residue. The reaction rate by default (for example: in atmosphere) depends on temperature as clamp01(1 / (0.002 * (TC + 273.0)1.6 + 0.05) / 5 for oxygen as an oxidizer, and clamp01(1 / (0.0025 * (TC + 273.0)1.01 + 0.05) / 5 for nitrous oxide. Thus, the maximum default reaction rate is 0.2 and is valid at temperatures below 211C when without nitrous oxide and 107C when enough nitrous oxide is present (>~5%). After that reaction rate decreases logarithmically. At temperatures above 460C, nitrous enriched fuel combusts faster (at approx. 2x rate) than oxygen only. At higher temperatures, the difference is even greater, thus making the reaction more efficient and violent. Some devices (like [[H2_Combustor|H2 Combustor]] or [[Kit_(Gas_Fuel_Generator)|Gas Fuel Generator]]) increases rate of reaction (to 0.9 i.e. 90% in both cases).

If a combusting gas mix contains Volatiles, NOS, and O2, they all will react proportionally at same rate, according to aforementioned reactions (i.e. at 90% reaction rate and ideally balanced mix, each component will decrease by 90% from it's original amount). When mix is unbalanced and have either excess of volatiles or oxidizers, then proportions decrease accordingly, i.e. with excess of volatiles, only the amount of volatiles corresponding to amount of oxidizers (2 per Oxygen, 1 per Nitrous Oxide) will decrease proportionally; with excess of oxidizers, similarly, only the amount of oxidizers corresponding to the amount of volatiles is decreased at reaction rate, i.e. oxygen reacts at half the rate of nitrous oxide.

Volatiles have a specific heat of 20.4 Joule / mol.

===Notes===
* The Specific heat of 20 Joule / mol is in-between the specific heat of Hydrogen and Methane.
* The actual Autoignition temperature of Chloromethane in Oxygen is 625 °C (1,157 °F; 898 K), the game grossly underestimated the iginition temperature by about 11 times.
* Seems that a concentration of Volatiles greater than 6% in an atmosphere it is lethal to plants, keep attention on that designing a greenhouse, because [[Kit (Advanced Composter)|Advanced Composter]] will release Volatiles during the process.
* Enthalpy of Hydrogen (H2) combustion is precisely 286 kJ/mol
* As far as rocketry is concerned, Volatiles have a mass of 62.5 mol/kg
* Given the above, Volatiles have a molar mass of 16, suggesting it really is methane (CH₄).

==Sources== 
Volatiles can be collected from the following sources:

{| class="wikitable"
|-
! Source !! Amount
|-
| [[Biomass]] || 8 mol
|-
| [[Ice (Volatiles)]] || 22 mol
|-
| [[Ore (Cobalt)]] || 1 mol
|}

Can be also obtainable by [[trading]].

= Description = 
<blockquote><q>Oxygen provides energy when released in combustion, and also bonds with hydrogen to create [[Water]]. It is created by [[plants]], as well as from processing [[Ice (Oxite)]]. It is highly flammable at low temperatures.</q> 
'''- Stationpedia'''</blockquote>

Oxygen, also referred to as O2, is the basic gas necessary for human survival. It is is released when smelting certain ore (such as [[Ore_(Gold)|gold]]) or by melting [[Ice_(Oxite)|Oxite]]. It is also produced by plants in [[Hydroponic_Tray|hydroponic trays]] or the [[Hydroponic_Station|hydroponics station]] when they photosynthesize.

= Details =
Oxygen will condense into '''Liquid Oxygen''' starting at {{Temperature|162}}. The boiling point of Oxygen is {{Temperature|90}} at 100 kPa.

Pure Oxygen auto-ignites at {{Temperature|573.15}} when in [[atmosphere]] at any pressure where [[Volatiles|volatile gases]] are present. This may be caused by activating a gas-powered [[Welder|welder]], engaging any type of crafting stations working with metal (such as an [[Autolathe|autolathe]]), or using any firearm, either of which will create a local temperature spike and the follow-up chain reaction.

Oxygen is mainly used in sustaining human life, either in the ambient atmosphere when your helmet is open, or in your suit's oxygen tank. Oxygen's other roles are in the creation of [[Fuel#Gas_Fuel|fuel]], as well as [[Nitrous Oxide]] through the use of a [[Nitrolyzer]].

== Notes ==
* When used as oxidizer in rocket fuel, oxygen has a mass of 62.4 mol/kg.

== Sources ==
You can collect Oxygen from the following sources:

! Source !! Amount
|-
| [[Ice_(Oxite)|Ice (Oxite)]] || 22.5 mol
|-
| [[Ore_(Gold)|Gold Ore]] || 0.2 mol
